Hello Jeff,
 
Have you seen this? Another new virus.

A New Virus Found In Rhode Island Mosquitoes... But No Signs Of West Nile Virus
 
PROVIDENCE - The State Department of Environmental Management (DEM) says there are still no signs of the West Nile virus in Rhode Island. However, some bird-biting mosquitoes trapped in the Ocean State have been found to be carrying another virus called Highland J. virus. Officials say that: "While this virus cannot be transmitted to humans, its appearance increases the likelihood of finding other viruses which are dangerous to humans such as Eastern Equine Encephalitis and West Nile viruses". The State says that for the time being, it still has no plans to spray.
 
West Nile virus was detected in a dead crow found in a park in Bostonís Jamaica Plain neighborhood over a week ago. Massachusetts state health authorities say a second dead crow, found in Hopkinton, also tested positive for the West Nile virus. However, none of the mosquitoes taken from the Boston pond where an infected bird was also found over the weekend have tested positive. Boston officials have begun anti-mosquito spraying.
 
The State laboratory in Massachusetts has been inundated with dead birds, which have been arriving in much greater numbers since the first dead crow was found. Officials with the State Public Health Department say that the lab is now getting about 300 dead birds a day, when it usually only gets about 12 birds a day.
 
The Rhode Island DEM said test results of 60 pools of mosquitoes and 10 birds for the West Nile virus are negative. There is a statewide action plan to address concerns with the virus. Testing has been conducted weekly since 30 May and will continue through the fall.

[Eastern equine encephalitis (EEE) virus and Highlands J. virus belong the _Alphavirus_ genus of the family _Togaviridae_ and these two viruses are not related to West Nile virus, which is a member of a different virus family, the _Flaviviridae_. Molecular studies suggest that Highlands J. virus is a recombinant New World alphavirus with the glycoprotein gene sequence derived from a Sindbis-like virus and the remainder of the genome from an EEE-like virus. The isolation of Highlands J. virus from mosquitoes does not increase the likelihood of isolation of West Nile virus, contrary to the above statement. -Mod. CP]

Ontario wants dead birds tested for West Nile virus as safety precaution -----------------------------------
 
TORONTO: Ontario residents are being asked to report any unusual bird deaths to their local health department as a precaution against the spread of West Nile virus. The provincial Ministry of Health has also asked its health units to gather all dead birds and test them or the virus, which is carried in a bird's blood and can be transmitted to humans by mosquitoes. The virus, which causes the potentially fatal disease encephalitis, had never been seen in the western hemisphere until it infected 62 people and killed seven in New York City last summer, including a visiting Toronto resident. As a precaution to monitor a possible spread to Canada, health officials have started surveillance plans.
 
"It has not been detected in Canada, but it could show up here. There's no question about that, but the risk of death in an automobile accident this long weekend, is still higher than the risk of infection by West Nile virus", said Dr. Gordon Surgeoner, a University of Guelph Entomology Professor
